| Abstract | 【目的】对甘蔗品种桂糖42号的种性及其高产稳产性进行分析与评价,为其大面积推广应用提供参考依据。【方法】以可代表广西蔗区70%土壤类型的金光农场为试验地点,选择高、中、低3种不同土壤类型的地块,以新台糖22号(ROC22)为对照,连续进行桂糖42号4年新植3年宿根共30点次的生产性试验;试验期间调查其主要农艺性状、抗性及产量表现,并采用高稳系数与变异系数相结合的方法分析其高产稳产性。【结果】桂糖42号新植蔗的萌芽率和茎径与ROC22接近,分蘖率、单位面积苗数和有效茎数高于ROC22,但差异均不显著(P>0.05,下同),株高则显著低于ROC22(P<0.05,下同)。宿根蔗的株高略高于ROC22,茎径与ROC22相当,单位面积苗数和有效茎数较ROC22有明显优势,与ROC22的差异达显著或极显著(P<0.01,下同)水平。桂糖42号抗螟虫和抗梢腐病能力与ROC22相当,抗黑穗病、抗倒伏能力及抗旱性强于ROC22。新植蔗和宿根蔗的平均蔗糖分为14.95%~15.36%,均高于ROC22,但差异未达显著水平。1~3年宿根蔗茎产量和糖蔗产量分别比ROC22增产28.86%~62.93%和28.98%~63.03%,其中第3年宿根仍有较高的蔗茎产量和蔗糖产量,分别达80.02和12.32 t/ha,4新3宿的平均蔗茎产量和蔗糖产量分别达95.32和14.43 t/ha,比ROC22极显著增产18.38%和18.86%。从高稳系数和变异系数来看,桂糖42号新植蔗的产量稳定性较ROC22略差,但宿根蔗和新宿平均的产量稳定性较高,较ROC22有明显优势。【结论】桂糖42号在广西金光农场表现出高产高糖、宿根性强、抗旱性好、脱叶性好及抗倒性强等诸多优良特性,适宜在广西及国内相同土壤类型蔗区进一步推广种植。 |

| Abstract_FL | [Objective]Varietal characteristics and high yield stability of sugarcane variety Guitang 42 were evaluated to provide scientific reference for large area planting of it.[Method]Representing 70% soil types in Guangxi sugarcane area,Jinguang Farm was selected as experiment site.High,medium and low soil types were chosen,and sugarcane cultivar ROC22 was as control.A total of 30 productive trials were conducted in 4-year planting seedlings and 3-year ratoon seed-lings of Guitang 42.Main agronomic traits,resistance and yield of Guitang 42 were investigated during the trial period,and its productivity and yield stability was evaluated by the high stability coefficient and coefficient of variation.[Result]For new planting seedlings,germination rate and stalk diameter of Guitang 42 were close to ROC22,but tillering rate,seedling number per unit area and effective stalk of Guitang 42 were higher,without significant difference(P>0.05,the same below).Seedling height of Guitang 42 was significantly(P<0.05,the same below)shorter than ROC22.In terms of ratoon crops,seedling height of Guitang 42 was slightly higher than ROC22,stalk diameter was close to ROC22,seedling number per unit area and effective stalk were greatly higher,with significant or extremely significant(P<0.01,the same below)difference.The resistance to borer and pokkah boeng disease of Guitang 42 were similar to ROC22,the resistance to smut,lodging resistance and drought resistance were all stronger than ROC22.Average sucrose content of planting seed-lings and ratoon seedlings were 14.95%-15.36%,which was higher than ROC22,but the difference was insignificant.Average of cane yield and sucrose yield of 1-year to 3-year ratoon seedlings increased 28.86%-62.93% and 28.98%-63.03% than ROC22.Especially in the 3-year ratoon seedling,cane yield and sugar yield reached 80.02 and 12.32 t/ha.Average of cane yield and sugar yield of 4-year plant seedlings and 3-year ratoon seedlings increased extremely signifi-cantly 18.38% and 18.86% than ROC22 and reached 95.32 and 14.43 t/ha.In terms of high stability coefficient and coeffi-cient of variation,sugarcane yield stability of Guitang 42 new plating seedlings was slightly worse than ROC22,but its yield stability of ratoon seedlings and average new planting seedlings had obvious advantages over ROC22.[Conclusion]Guitang 42 is characterized by high yield,high sucrose,strong ratoon ability,high drought resistance,easy defoliation and good lodging resistance,which is suitable for further promotion in sugarcane planting areas of Guangxi and even China with the same soil types. |
